Embodiment Construction
[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention. In order to clearly describe the solutions provided by the embodiments of the present invention, the embodiments of the present invention will be described below.
[0014] To describe accurately, the concept of the radius of the roll shaft is pointed out in the description of the present invention, and the radius of the roll shaft is from the center of the roll shaft to the outer edge 3 of the roll shaft. The outer edge 3 of the roller shaft is the presence of teeth on the circumference of the roller shaft in the present invention.

The invention provides an eight-tooth set non-woven fabric roller with large R angles. The non-woven fabric roller is composed of a roll shaft and a non-woven fabric body, the roll shaft is provided with eight same grooves to form eight same teeth on the roll shaft, large R angles are arranged on the two sides of each tooth, and the non-woven fabric body is provided with corresponding sets on theroll shaft; the eight grooves on the roll shaft are distributed on the outer edge of the roll shaft at equal interval, the bottoms of the grooves are flat, the depths of the grooves are the same on the radius of the roll shaft, the size of the bottom surfaces of the grooves is same, the two side edges of the grooves are symmetric, the side edges of the grooves perpendicularly extend to the middlesof the grooves from bottom to top and then bend outside the edge of the roll shaft in an arc-shaped mode to form the R angles, and the lengths of the R angles on the radius are 38%-48% of the depthsof the grooves. The eight-tooth set non-woven fabric roller with the large R angles has the advantage that combination of the roll shaft and the non-woven fabric is bonded in a stronger mode.
Description
technical field [0001] The invention relates to the field of plate processing, in particular to an eight-tooth suit non-woven roll with a large R angle. Background technique [0002] The non-woven roll is a thicker non-woven fabric set on a roll shaft, which refers to a cylindrical part that can roll on the machine, and can evenly press the extruded or calendered film and the substrate together. [0003] Most of the current non-woven rolls are imported, and now there are some manufactured products in our country. At present, there are non-woven rollers on the market with four protrusions on the roller shaft or large grooves on the roller shaft to fix the inner side of the non-woven fabric. The problem is that it is easy to pierce the inner side of the non-woven fabric. , causing looseness between the inner side and the roller shaft. We need to design a more durable non-woven roll in production practice. Contents of the invention [0004] In order to achieve the above-me...
